Abstract
The invention discloses a two-end acting type spring chuck to solve the problem of inconvenience of clamping of shaft workpieces in the prior art. The spring chuck comprises a chuck body, a first tapered sleeve, a second tapered sleeve, a lock nut in threaded connection with one end of the chuck body, a collet matched with the first tapered sleeve and the second tapered sleeve and a lining between the chuck body and the lock nut. A spring is arranged between the first tapered sleeve and the second tapered sleeve, one end of the lock nut is in threaded connection with the chuck body, the other end of the lock nut is in threaded connection with the lining, the lining is connected with the second tapered sleeve internally and connected with the lock nut externally, an open groove extending from the head to the middle axially is formed in the collet, and an elastic rubber layer is filled in the open groove.
Description
Technical field
The present invention relates to the clamping device technical field of Machining of Shaft-type Parts, be specifically related to a kind of two ends action type collet.
Background technology
When machine tool chief axis working shaft-like part, need the clamping device of axle class special use to its clamping position, at present, often there is following problem in the clamping device that the manufacturing procedure of shaft-like workpiece adopts: in the time of need to carrying out process operation along circumferential a plurality of angles to shaft-like workpiece, because clamping device can not regulate clamping angle, or the structure of adjusting angle is more complicated, makes troubles to operation, reduce working (machining) efficiency.
Summary of the invention
The invention is intended to provide a kind of two ends action type collet, to solve the problem of prior art axis class clamping workpiece inconvenience.
Two ends action type collet in this programme, comprises clamp, also comprises the first tapered sleeve, the second tapered sleeve, the locking nut being connected with clamp threaded one end, the collet chuck coordinating with the first tapered sleeve, the second tapered sleeve, the lining between clamp and locking nut; Between the first tapered sleeve and the second tapered sleeve, be provided with spring, locking nut one end is threaded with clamp, the locking nut other end is connected with bush threads, in lining, connect the second tapered sleeve, the external locking nut of lining, collet chuck is provided with the open slot extending axially from the head to middle part, in described open slot, is filled with elastic rubber layer.
Compared with prior art, advantage of the present invention is: under duty, tighten locking nut, by lining, promote the second tapered sleeve, and then Compress Spring promotes the first tapered sleeve, thereby make collet chuck clamp part, owing to having filled elastomeric layer in the open slot of collet chuck, thereby open slot is carried out to elastic packing, not only can not affect the clamping effect of collet chuck, can also in processing parts process, effectively prevent that iron filings from entering and being accumulated in open slot from open slot, thereby improved the clamping precision of part, unclamp locking nut, under spring action, the second tapered sleeve resets, collet chuck unclamps workpiece, the present invention is simple in structure, cost is low, and processing ease, convenient mounting and clamping.
Further, be also provided with key between lining and clamp, key is annular, is stuck between lining and clamp, limits lining, prevents that lining from departing from clamp.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of two ends action type collet embodiment of the present invention.
The specific embodiment
Shown in Fig. 1, the two ends action type collet in the embodiment of the present invention, comprises clamp, also comprise the first tapered sleeve 1, the second tapered sleeve 4, the locking nut 5 being connected with clamp threaded one end, with the collet chuck 3 that the first tapered sleeve 1, the second tapered sleeve 4 coordinate, the lining 6 between clamp and locking nut 5; Between the first tapered sleeve 1 and the second tapered sleeve 4, be provided with spring 2, locking nut 5 one end are threaded with clamp, locking nut 5 other ends are threaded with lining 6, in lining 6, connect the second tapered sleeve 4, the external locking nut 5 of lining 6, collet chuck 3 is provided with the open slot extending axially from the head to middle part, in described open slot, is filled with elastic rubber layer, is also provided with key between lining 6 and clamp.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic is not done too much description at this.Should be understood that; for a person skilled in the art, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (2)
1. a two ends action type collet, comprises clamp, it is characterized in that: also comprise the first tapered sleeve, the second tapered sleeve, the locking nut being connected with clamp threaded one end, the collet chuck coordinating with the first tapered sleeve, the second tapered sleeve, the lining between clamp and locking nut; Between the first tapered sleeve and the second tapered sleeve, be provided with spring, locking nut one end is threaded with clamp, the locking nut other end is connected with bush threads, in lining, connect the second tapered sleeve, the external locking nut of lining, collet chuck is provided with the open slot extending axially from the head to middle part, in described open slot, is filled with elastic rubber layer.
